Which iteration of The Sims did you start from?

I've known about the Sims for a while (I remember the adds for the original Sim City on TV) but other than messing with the CAS demo for Sims 3 (which eventually led me to Daz Studio and CG character art that way) and playing with Sims Medieval a few times, I didn't actually start playing Sims seriously until Sims 4 was free on Origin.

And I have no regrets.
